Exploration of surface milling machining process of C/SiC composites based on quality improvement

Abstract

C/SiC composites have the advantages of high strength, oxidation resistance and high temperature resistance, which are widely used in aerospace high temperature structures. However, the machining apparent quality has also become an important factor limiting its application. Therefore, this paper investigates the effects of cutting force, tool parameters and tool wear on the apparent quality of ultrasonic vibration milling of C/SiC composites. And the effect of tool selection and tool path on the milling surface roughness of C/SiC compliant materials is proved by experiments. In order to provide certain reference for the improvement of the surface milling quality of C/SiC composite materials.
